FIG 8. 63-year-old man with right intracanalicular acoustic schwannoma.
A–E, A mass (arrow) is seen on unenhanced (A) and contrast-enhanced (B) 3D-FASE (5000/241.6/1) images, on unenhanced (C) and contrast-enhanced (D) 3D-CISS (16/8/1) images, and on contrast-enhanced 3D-SPGR (23/10/1) image (E). Note that the signal of the mass is not influenced by contrast material on the 3D-FASE image, but enhancement is present on the 3D-CISS sequence.
